Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was moderate during the last 24 hours, with an M1 flare detected from NOAA Active Region (AR) 3376 (magnetic type Beta, Catania group 86) today 02:03 UTC. Most of the C-flaring activity came from NOAA AR 3373 (magnetic type Beta-Gamma, Catania group 81), while the brightest C-class flares came from NOAA AR 3380 (magnetic type Beta, Catania group 95), with two C3 flares today at 07:00 and 08:21 UTC. Further C-class flaring activity is expected, with a chance of an isolated M-class flare in the next 24 hours.

Koronalny wyrzut masy

No Earth-directed Coronal Mass Ejections (CME) were observed in the last 24 hours. A halo CME can be seen in LASCO/SOHO coronograph data starting from yesterday 18:12 UTC, however this is a back- sided event.

Wiatr słoneczny

The Solar Wind (SW) conditions remain in a slow SW regime during the last 24 hours. The SW speed varied between 350 and 460 km/s in the last 24 hours. The total interplanetary magnetic field (Bt) varied between 3 and 7 nT and its North-South component (Bz) ranged between -6 and 6 nT. The interplanetary magnetic field phi angle was almost exclusively directed towards the Sun during the past 24 hours. A glancing blow from a Corona Mass Ejection (CME) is expected to arrive in the next 24 to 36 hours, however, it is not expected to have a major effect to the SW conditions.

Geomagnetyzm

Geomagnetic conditions were both globally and locally unsettled for short periods (NOAA Kp 3- and K BEL 3) and for the rest of the time quiet (NOAA Kp 1 to 2+, K BEL 1 to 2) during the past 24 hours. They are expected to become unsettled to active in the next 24 hours.

Poziomy przepływu protonów

A proton event was detected yesterday by the GOES-18 satellite lasting from 18:00 to 23:00 UTC. However, this event was weak and the 10 MeV proton flux reached but did not exceed the 1000 pfu threshold. The 10 MeV proton flux is expected to remain below the 1000 pfu threshold for the next 24 hours.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux remained below the 1000 pfu alert threshold and is expected to remain below this threshold during the next 24 hours. The 24h electron fluence was at nominal levels and is expected to remain so.
